- 1CoordinatePairs of numbers which specify the location of a point on the coordinate plane.
- 2Coordinare PlaneA plane formed by the intersection of a horizontal number line (x-axis) and a vertical number line (y-axis).
- 3Dependent VariableThe y values in a function; also known as (a.k.a.) the output
- 4FunctionA relation where there is exactly one output for every input.
- 5Function RuleAn expression or equation that shows the operations performed on the independent variable (input) to determin the value of the dependent variable (output).
- 6InputThe x-values in a relation or function, a.k.a. the independent variable.
- 7Independent VariableThe x-values in a function; a.k.a. the input
- 8linear Functiona function that increases or decreases at a constant rate; a straight line.
- 9Nonlinear FunctionA function that does NOT increase or decrease at a constant rate; not a straight line.
- 10OriginWhere the x- and y-axis meet; coordinate (0,0).
- 11OutputThe y-values in a relation or function; a.k.a. dependent variable.
- 12Rate of ChangeThe ratio of the change in the y-value and the change in the x-values; change in y over change in x.
- 13RelationAny set of ordered pairs; a set of input and output values.
- 14Vertical Line TestA test used to determine whether a relation is a function. A graph is a function if vertical lines can be drawn through a graph and only touch the graphed line once.
- 15x-axisThe horizontal axis in a coordinate plane.
- 16y-axisThe vertical axis in a coordinate plane.
